Digital leadership skills and associations with psychological well-being
No full textDue to increasing digitalisation, today’s working world is changing rapidly and provides managers with new challenges. Digital leadership is an important factor in managing these challenges and has become a key concept in the discussion about what kinds of skills managers need for digital transformation. The main research question our study explored was if digital leadership is associated with psychological well-being in upper-level managers. Based on a qualitative pilot study and relevant literature, we developed a new scale for digital leadership in managers. We conducted an online survey with a sample of 368 upper-level managers from a large German ICT-company. Using a stepwise logistic regression analysis, potential effects of digital leadership on psychological well-being (WHO-5) were analysed. Logistic regression analyses showed that better skills in digital leadership were significantly associated with higher well-being. Results also showed that gender, age and managerial experience had no effect in our model. Our study provides a valuable insight into the association between digital leadership and well-being in managers. However, further research is necessary to validate the newly developed scale for digital leadership and to confirm a causal effect in the relationship between digital leadership and well-being.</p

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Issues of 'life' and 'death' for patients receiving palliative care-comments when confronted with a research tool
No full textPurpose To be able to study the desire for hastened death (DhD) in patients receiving palliative care, research tools reflecting the thoughts of patients are needed. In order to better understand what issues of "life" and "death" mean to patients receiving palliative care in Germany, we analysed their spontaneous comments during a validation study of the German version of the Schedule of Attitudes Towards Hastened Death. Method Field notes and transcripts of 39 interviews were analysed by thematic analysis. Method Field notes from 32 patients were related to differentiating either an acute or a non-acute DhD. Furthermore, the patients' comments were categorized and the distribution of codes analysed, leading to three types of comments: (a) longing for life excluding a hastened death, (b) wanting to live on, but perceiving death as an option, and (c) longing for death, but struggling for life. Conclusion The existing construct of an increased DhD may benefit from a further differentiation between "non-acute" and "acute." In addition, it could be helpful to conceptualize "will to live" and "desire for death" not as polarities from one dimension (two sides of the same coin), but to think them as two independent dimensions.Deutsche Forschungsgemeinschaft DFG [Vo 497/4-1
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Costs of HIV in germany
No full textHintergrund: Mit der Einführung der hochaktiven antiretroviralen Therapie (ART) in den neunziger Jahren hat sich der Verlauf der HIV-Infektion deutlich geändert. Daher können sowohl die Letalität als auch die Morbidität durch die HIV-Infektion deutlich gesenkt werden. Die HIV-Infektion stellt nunmehr eine chronische Erkrankung mit lebenslangem Behandlungsbedarf dar. Die bisher veröffentlichen Daten zu den Krankheitskosten der HIV-Infektion in Deutschland sowohl aus gesellschaftlicher Perspektive als auch aus der Perspektive der gesetzlichen Krankenversicherung (GKV) sind sehr heterogen und wenig detailliert. Fragestellung: Ziel war es, die Krankheitskosten der HIV-Infektion in Deutschland anhand eines in HIV-Schwerpunktpraxen behandelten Patientenkollektivs empirisch zu erheben sowie die Determinanten der Krankheitskosten zu identifizieren und zu quantifizieren. Methoden: Es wurde eine 18-monatige prospektive, multizentrische, gesundheitsökonomische und klinische Evaluation durchgeführt. Zur Berechnung der Krankheitskosten wurde ein Preisgerüst für die gesellschaftliche Perspektive und die Sicht der GKV aufgestellt. Das Basisjahr war 2008. Zur Beantwortung der Frage nach den Determinanten der Krankheitskosten wurden vier lineare Regressionsmodelle aufgestellt. Die abhängigen Variablen stellten die Gesamtkosten aus gesellschaftlicher Sicht und aus Sicht der GKV dar. Folgende Variablen wurden als unabhängige Variablen mit in das Modell einbezogen: Geschlecht, CD4 Zellzahl, Alter in Jahren, acquired immunodeficiency syndrome (AIDS)-definierende Ereignisse, andere relevante Begleiterkrankungen, Therapieschiene, Übertragungsrisiko, Zeit seit der Erstdiagnose in Jahren, Zentren. Zur Validierung der Ergebnisse wurde ein nicht-parametrisches Bootstrapping durchgeführt. Ergebnisse: 518 Patienten aus 17 Zentren konnten in die Evaluation miteinbezogen werden. Die durchschnittlichen Gesamtkosten aus gesellschaftlicher Perspektive betrugen 23.300 € pro Patient pro Jahr. Die GKV musste im Durchschnitt für jeden Patienten 19.100 € aufbringen. Die HIV-Medikation hat einen Anteil an den Gesamtkosten von 80% (gesellschaftliche Perspektive) bzw. 89% (Perspektive der GKV). In den Regressionsmodellen lassen sich vier signifikante Determinanten der Krankheitskosten identifizieren: das weibliche Geschlecht, intravenöser Drogengebrauch als Übertragungsweg, eine geringe CD4- Zellzahl sowie der Erhalt keiner ART und der mehr als zweimalige Wechsel der ART. Weiterführend liegen signifikante Unterschiede in den Krankheitskosten zwischen den 17 Zentren vor, die insgesamt an der Studie beteiligt waren. Insgesamt können zwischen 27 und 31% der Krankheitskosten in den vier aufgestellten Modellen erklärt werden. Fazit: Die ermittelten HIV-Krankheitskosten stellen eine geeignete Datengrundlage für die Durchführung von vergleichenden gesundheitsökonomischen Evaluationen dar. Die Identifikation relevanter kostentreibender Determinanten im Rahmen der vorliegenden Studie kann überdies dazu genutzt werden, die potentiellen Krankheitskosten von bestimmten Patienten zu prognostizieren. Durch die Information darüber, welche Determinanten die Gesamtkosten in welcher Höhe beeinflussen, kann auch bei einer veränderten Zusammensetzung der zu betrachtenden Population eine Abschätzung über die Höhe der anfallenden Kosten erfolgen
